II SPECIFIC STIPULATIONS

1 Object of approval and area of application

The MAX FRANK Egcodorn (see annex 1) is a connection element between construction components made of reinforced concrete according to DIN EN 1992-1-1:2011-01 and is used for the planned transmission of shear forces.

The use is restricted to standard concrete of strength class C20/25 up to C50/60.

The Egcodorn may be used as a flush connection element between reinforced concrete construction components which meet the requirements on the bending limitation according to DIN EN 1992-1-1:2011-01, section 7.4.2, under mainly static load.

The admissible environmental conditions depend on the exposure classes (DIN EN 1992-1-1, table 4.1) as well as on the corrosion resistance classes of the types of steel used indicated in the national technical approval no. Z-30.3-6.

The Egcodorn consists of a dowel element and the related sleeve element which are equipped with an anchor element for introducing the load into the concrete. The anchor element consists of a front plate with two differently bent loop brackets.

The Egcodorns are standardised in the types 40, 50, 70, 95, 100, 120, 150, 170, 210, 300, 350 and 400, each in regularly relocatable N-version and in cross-relocatable Q-version.

With the Egcodorn N, the sleeve is the round counterpart of the dowel so that only movements in the direction of the longitudinal axis of the dowel are possible.

With the Egcodorn Q, the sleeve is rectangular so that an additional relocation capability vertically to the longitudinal axis of the dowel is possible.

The joint width between the components to be connected may amount to up to 80 mm.

2 Stipulations for the construction product

3 Specifications regarding the design and dimensions

DIN EN 1992-1-1 applies unless otherwise specified below. DIN EN 1992-1-1 is always applicable in combination with DIN EN 1992-1-1/NA in its respective current edition.

3.1 Specifications regarding the design The transmission (distribution and intake) of the forces transferred by the “Egcodorn” to the

downstream components is to be verified for each individual case. The transmissible shear forces are only applicable to the indicated joint widths. If the possibility that the calculated joint widths are exceeded cannot be excluded, the transmissible shear forces of the next greater joint width are to be applied or the transmissible shear forces determined through linear interpolation. The “Egcodorn N” can exclusively take up longitudinal relocations along the dowel axis. The “Egcodorn Q“ can take up both longitudinal as well as horizontal transverse relocations along the dowel axis. “Egcodorns” may only be installed into plates with straight edges. In all other cases, for every “Egcodorn”, a suitable relocation capability is to be verified. When installing the “Egcodorns” across a corner, suitable relocation abilities are to be verified.

560PZ3104-INTGB-0618


Page 7 of 9 | 13 June 2018

The longitudinal armouring Asy at the edge of the plates may be determined assuming a continuous edge beam with span widths according to the spaces between the dowels. When attaching the Egcodorn to the wall, a stirrup armouring in accordance with dx according to annex 12 is to be aligned (please also refer to annex 13).

3.2 Specifications regarding the dimensions The application is restricted to standard concrete of the strength classes C20/25 up to

C50/60. For the concrete strengths > C20/25, the nominal resistance values are indicated in annex 9, tables 1 and 2, and are applicable to all dowels in good compound systems for all previously indicated concrete strength classes. An increase in the load capacities when using higher concrete strengths than C20/25 is inadmissible. The verification of the proof in the SLS is not provided hereby.

3.3 Verifications in ultimate limit state 3.3.1 Steel failure

The nominal load capacity values for the dowel cross-section and the anchor elements are indicated in annex 9, tables 7 and 8, depending on the joint width. As calculated joint widths, z = 10mm, z = 20mm, z = 30mm, z = 40mm, z = 50mm, z = 60mm, z = 70 mm or z = 80mm shall be applied. Intermediate values may be linearly interpolated. The diameter of the anchor element stirrup is to be selected in accordance with annex 9, table 9, while the diameter of the cap stirrup is to be selected according to annex 9, table 10. The cap stirrup can be omitted with plate thicknesses of greater than or equal to hK according to annex 4.

3.3.2 Punching verification The punching verification according to DIN EN 1992-1-1, section 6.2 and 6.4, together with

DIN EN 1992-1-1/NA, NCI on 6.2 and 6.4 applies. The critical circular section is to be determined in accordance with annex 12. For verification purposes, concrete strengths up to C50/60 may be applied.

3.3.3 Concrete edge failure The concrete edge failure verification is considered complied with if the regulations of this

national technical approval are observed.

3.3.4 Consideration of friction forces The existing friction forces are taken into consideration in the tables in annexes 9 and 10.

When determining the armouring to be provided at the construction site, the friction forces do not have to be considered.

3.4 Verification of the serviceability limits states 3.4.1 Limitation of crack widths The crack width verification of the plate edge beams is to be implemented in accordance

with DIN EN 1992-1-1, section 7.3, taking into consideration the respective section of DIN EN 1992-1-1/NA. If, in the wall, transverse tension occurs in the direction of the shear force dowel load and if the crack width in the direction of the shear force dowel load is not reduced to wk < 0.2mm, the load capacity of the dowel is to be reduced by 1/3.

3.4.2 Limitation of deformation The “Egcodorn” may be used as shear force coherent connection element between the steel

concrete components which comply with the requirements on the bending limitation according to DIN EN 1992-1-1, 7 4 2, taking into consideration DIN EN 1992-1-1/NA, NCI on 7.4.2 (2).

560PZ3104-INTGB-0618


Page 8 von 9 | 13 June 2018 3.5 Constructive design 3.5.1 Factory design

The surface of the sleeve and dowel shall be treated at the factory in order to minimize the friction. On the construction site, the surface may not be changed in a way that the finish roughness is increased. The edges of the sleeve opening must be burr-free.

3.5.2 Construction -side design The minimum thickness of components hmin according to annex 4 are to be complied with. The alignment of the minimum armouring in the punching cone is stipulated in annex 12. The relation of the plate thickness to the Egcodorn diameter h/Dk >7 is to be complied with. The relation of the diameters of the longitudinal bars and brackets dsy / dsx,1 > 1 is to be complied with. The cap stirrup according to annex 9, table 4, is to be aligned within a distance of 20mm from the end of the shear force dowel and/or within a distance of 80mm from the end of the sleeve.

4 Implementation specifications

When installing the “Egcodorns”, the minimum distances hmin/2 of the upper and lower edges of the components to be connected towards the centre of the dowel may not be exceeded. It is to be thoroughly ensured that no angle deviations occur between adjacent “Egcodorns”.
